Phase Change Materials (PCM) | ENRG Blanket
High-Performance Building Insulation
The Science of Latent Heat Storage
Phase Change Materials (PCMs) are engineered substances that store and release significant thermal energy during the transition between solid and liquid phases. Unlike traditional insulation that only slows heat transfer, our ENRG Blanket™ acts as a “thermal sponge,” utilizing the Latent Heat of Fusion to absorb excess heat before it impacts your indoor environment.
Why BioPCM®?
While many competitors rely on petroleum-based Paraffin Wax or corrosive Salt Hydrates and Fatty Acids in their energy storage applications, Biz Reps provides BioPCM®—a proprietary, plant-based smart material for thermal management.
- 100% Bio-based: USDA Certified Biobased Product.
- Non-Toxic & Non-Corrosive: Sustainably sourced and safe for all building types.
- 100+ Year Useful Life: Engineered to outlast the building itself through thousands of phase change cycles.
What is the ENRG Blanket?
ENRG Blanket® is a drop-in solution powered by our proprietary BioPCM® platform which absorbs and releases significant thermal energy at a specific design temperature resulting in lower heating and cooling energy use by up to 35%. The ENRG Blanket is non-toxic and non-corrosive made of a sustainably sourced plant-based phase change material powered by BioPCM®, a proprietary phase change material developed and manufactured by Phase Change Energy Solutions.
ENRG Blanket is a proven and cost-effective means to reduce energy consumption. It works together with traditional HVAC units all while maintaining a consistent and stabilized temperature in accordance with industry standards.
How It Works: Optimizing the HVAC Lifecycle
The ENRG Blanket™ creates a thermal buffer that delays the call for mechanical cooling. By absorbing heat at specific target temperatures (73°F, 77°F, 80°F, or 84°F), it optimizes the entire HVAC system:
- 25-35% Reduction in total HVAC power consumption.
- 15-20% Reduction in HVAC runtime.
- 20-25% Reduction in cycling frequency, extending equipment lifespan and reducing mechanical wear.
In most locales, savings from ENRG Blanket will return its fully installed cost in less than four years, and in many cases less than three. Additional savings are realized through peak load shifting in locales that charge demand fees, increased HVAC life-expectancy and reduced maintenance and repair costs.
ENRG Blanket consumes no power and requires no maintenance to provide consistent power energy savings over its estimated useful life of more than 100 years.
By increasing efficiency, ENRG Blanket can help your team reduce operating expenses and free up resources to support growth, while also addressing global and corporate concern about the impact of power consumption on CO2 emissions, air pollution and climate change.

Types and Composition of PCMs
Grids)
ENRG Blankets® may be installed over ceiling panels in new buildings or as a retrofit solution for existing buildings to lower HVAC demand. Blankets can also be installed in a single room or zones to mitigate “hot office syndrome.” Works well in high performing buildings with minimal disturbance to occupants.
ENRG Blanket® may be installed in new buildings and during renovations of interior spaces. It can be placed under framed ceilings, before drywall application, to lower energy demands for improved occupant comfort.
Benefits & Advantages
- Reduce reliance on HVAC equipment
- Reduces HVAC power consumption by up to 40% with reduced HVAC cycling thus reducing operating costs
- Reduce peak-demand
- Reduce CO2 emissions and your carbon footprint, Biopic reduced annual power consumption by more than 10,000,000 kWh — a CO2 emissions equivalent to 800,000 gallons of gasoline consumed or 7.5 million pounds of coal burned.
- Attractive payback period savings from ENRG Blanket will return to its fully installed cost in under four years in most cases.
- Improve building comfort by regulating indoor temperatures.
- The ENRG Blanket offers passive temperature control, requiring no power and no maintenance providing energy savings throughout its useful life of more than 100 years.
- Made from environmentally friendly, derived from naturally occurring, food grade substances
- Long life of performance, no degradation in melting temperature or thermal energy storage after thousands of freeze/melt cycles (100+ years)
- MADE in the USA, BioPCM is manufactured and packaged in Asheboro, NC.
ENRG BlanketTM 5-year comprehensive warranty
Phase Change Energy Solutions warrants its ENRG Blanket products, (including BioPCM®), to be free from manufacturing defects and defects in workmanship for a period of 5 years from date of sale. Additional terms and conditions apply. Please refer to complete warranty terms.
Application and Integration in Building Materials
PCMs are incorporated into building materials in the construction industry including building components like ceiling tiles. The large surface area of the ceiling plane is considered ideal for PCM placement.
The ENRG Blanket was designed as a retrofit to existing interior walls/ceiling with 24” x 20” rugged BioPCM® panels that quickly Snap in and out. The Installation can be completed in as little as 2 hours and require zero maintenance. The transition point can be tuned to customer specifications.
Because they add thermal mass back into the structure they can also be integrated into insulation products that are laid on top of existing attic insulation or suspended ceiling tiles. Some newer composites can even be added to building components and materials like paint or used as 3D-printable “ink” for building components installed in a diverse range of commercial and residential buildings.
With millions of square feet installed globally, the ENRG Blanket™ is a proven retrofit and new-construction solution for:
- Fortune 100 Companies and global banking institutions.
- Military Bases and government facilities.
- Cold Chain Logistics: Ensuring safe transport for food and pharmaceuticals.
